Living and working within a system of architectural behemoths and concrete streets can be taxing, to say the least. And for many city-dwellers, a few patches of green can be a celebrated refuge from the urban landscape.

Through a study that spanned 18 years, researchers from University of Exeter Medical School discovered that people who moved to areas with more green space improved their overall well-being and happiness. So even if you aren’t looking to pack up and head to the country, scouting out cities with some form of natural catharsis can literally do you a lifetime of good.

We’ve teamed up with Citi to showcase these impressive nature-filled utopias in the world’s greatest cities, and recognize the positive impact they have on local residents.

Lurie Garden: Chicago, IllinoisHistory and features: Part of the city’s Millennium Park, this public garden celebrates Chicago’s motto Urbs in Horto, latin for “City in a Garden,” giving a nod to the swampland and marshes upon which the city was built. The land used to develop the garden and the larger park was originally under the jurisdiction of the Illinois Central Railroad and at one point considered "an urban wasteland" by many. The Lurie Garden and the rest of Millennium Park opened to the public in 2004 and have since won awards such as the Award of Excellence from the American Society of Landscape Architects. Size: Five acres

Boston Common: Boston, MassachusettsHistory and features: Considered to be the oldest park in the United States, Boston Common once played host to grazing cattle, public hangings, and British army camps before the American Revolution. Martin Luther King Jr. and Gloria Steinem are just a few of the park’s famous speakers that have addressed crowds in the park. The Common is also a part of the 2.5 mile long Freedom Trail which leads history lovers down a route of 16 historical sites including the grounds as an important part of America’s past. Size: 50 acres

The High Line: New York, New YorkHistory and features: Not too long ago, this park was just elevated train tracks that ran from 34th street to Spring street. A train transporting frozen turkeys in 1980 was the last locomotive to run on the High Line. After that, residents of the Chelsea neighborhood banded together to fight demolition of the tracks and encouraged a transformation into public space. The first section of the rail was reopened as a public park in June of 2009 and the last section was opened to the public on September 21, 2014. Most of the plants present on the High Line are those that sprouted naturally during the 25 years of disuse adding to the growing beauty of what was once a very industrial area of the city. Size: 395 acres
